Very helpful customer service, they helped me 2 separate times in 2 days both times they solved the issues in no time at all. The first was integrating the Shopify cart to monster as the shop cart icon to avoid confusion and the second was helping resolve an issue with my gift tiers. Thanks team!

Really responsive and helped me solve an issue in my setting between Monster Cart and Shopify in minutes.

I've always had such an amazing experience with Monster Upsell. The customer service team are swift with their replies and so helpful. Charlene is fabulous. A super easy app to integrate into your store. Highly recommend

Angelica was very helpful in troubleshooting and fixing up the issue when we had trouble setting up the free gift offer. Response time is very quick and she was able to get it sorted in no time.

Looks cool but I kept experiencing huge delays between clicking the cart or adding a product and the cart actually opening. Chatted with customer service twice but they said it was functioning normally. Also ran into issues where items would not add to the cart. Had to stop using it. Not sure if it was my theme because other people seem to have a good experience with this app.

So far we're loving it! We had a minor issue with a gift with purchase promotion we were running but the issue was swiftly resolved by the customer service team and our campaign was up and running asap.

Such a game changer! Love the simplicity and effectiveness of this app - also the support team were really fast to solve my issues during set up!

Monster Cart Upsell is by far the smoothest experience I’ve had on Shopify. The setup was almost too easy – it literally took me just a few minutes to get it up and running, with no need to mess around with code or complicated settings. What really blew me away was the customer support. I had a small question about customizing the design, and their support team replied almost instantly – super friendly and helpful. They provided clear guidance and helped me get everything just the way I wanted. The cart itself? It looks amazing. Super modern, clean, and very detailed – everything from product add-ons to discounts and custom messages blends perfectly into the cart design. My conversion rate has already gone up, and the whole shopping experience feels much more premium for my customers. If you're on the fence – just install it. You won’t regret it. – Happy store owner

When I fist emailed the team asking them about pricing I got an email pretty quick, I emailed back to confirm a few things but did not get a response which was disappointing. In the end I decided to just try it anyway. So far so good, It was a little funny to set up. Overall though I just had to make sure I was going step my step. I had some issues with how the shipping slider looked and I was able to get some help on this which was great so I really appreciated that quick turn around. I have not seen any amazing conversations or increase as yet in AOV however, I am quite a new store and also I have only one campaign being used so these might be playing into that. I will see how I go and use some other campaigns and see if this helps with my conversions/AOV ect. would recommend trying it out and just seeing if it right for you.

Great app & team. Customer service is always ready and happy to help with any problems. Charlene is lovely and always a pleasure to work with.
